Abstract
A cascade heat pump system is configured with variable-speed compressors which allow operation at a high system coefficient of performance for a given thermal load. An electronic control module may be utilized to dynamically vary the speed of the compressors to achieve maximum energy efficiency. Variable-speed fans or blowers may also be used.
